The English periodicals have been teeming with accounts of expe- 

 riments with guano for the past five years ; but as their climate and 

 course of cropping are so entirely different from our own, we do not 

 think it advisable to notice them further than by saying, that when 

 properly applied in an unadulterated state, the results are highly sa- 

 tisfactory, and prove it superior to most other manures, and we have 

 no doubt the same would follow in this country, particularly on poor 

 soil. On rich land, or such as has been highly manured, the appli- 

 cation of guano would be of little benefit. It suits alike, grass, 

 grain, root crops, flowers, and shrubs ; and owing to its great conden- 

 sation of fertilizing substances in a small bulk, it is particularly valu- 

 able and convenient in the conservatory and garden. 



Mr. Bartlett has been so obliging as to send us a bag of guano re- 

 cently imported, and we shall take pleasure in furnishing any of our 

 friends with a few pounds of it, who may be desirous of making ex- 

 periments. It is so pow^erful a manure that it must be used in very 

 moderate quantity, say from 100 to 200 lbs. per acre, otherwise it 

 "will kill the crop to which it is applied. We would recommend 

 mixing it under cover from rain, in thin layers of earth, and after it 

 has lain a short time, toss over the compost very minutely, and 

 then apply it to the crops. 



Dr. Underbill, of Croton Point : The culture of the grape is one of 

 the subjects under discussion. I am wholly unused to public speak- 

 ing. I do not recollect to have addressed an assembly before. I 

 take a deep interest in the culture ofthe grape. It is now several 

 years since I began to devote myself to it ; I have made it my great 

 object to establish its success in open field culture, from whence alone 

 the great body of the people can be supplied with this delicious and 

 salutary fruit. Great commendation is due to those who produce it 

 in their hot-houses. Boston is distinguished for her success in this.
